I need to design a PCB layout to a system using an isolated communication with optocouplers, what means that I need separated ground areas, each one on one side of the communication that I want to isolate. So, is that possible to do it? How could I do it in a simple way?

You can solve your problem using the ground terminal in both sides of your schematic as the image below.
The point is that in the layout process you have to draw two different ground areas and just ignore the link between them as is shown in the image below.
